The original values were for a US ecosystem that is less productive than that of the RIFA impact zone, & assessed for a society whose environmental preferences are similar to Australia's.  Subjective measures of the RIFA impact on specific ecosystem values were used to discount the transferred ecosystem-service values according to the expected spread of the ants.  The present value of RIFA damage in the modelled impact zone has an indicative figure of around $43 billion dollars, with an unknown error margin.  This figure would be significantly higher if spread outside the impact zone were also considered.  The flows of undiscounted costs & benefits of RIFA eradication within the modelled impact zone are illustrated.]1 aAntony, G.1 aScanlan, J.1 aFrancis, A.1 aKloessing, K.1 aNguyen, Y.  uhttps://antkey.myspecies.info/id/node/33430
